These pictures are really interesting. The first place C and H both look like English Orps of today. The third place Orps look like our current SOP Orps. How did that happen?? Look at the top and bottom lines.
The first place cock has a flat spot on the lower breast and a tail break....that is not what you want in any kind of Orp. the three females have pretty the much same bottom line, the first two have a tail break and the third place bird's tail is too low for any kind of Orp.. That is how I see them as a licensed APA/ABA judge.
